The development of AT4CS HP was dedicated to providing infantry soldiers with the means to use the unique and complex environment of the urban battlefield to their full advantage in defeating a mechanised enemy. The AT4CS HP is an anti-armour weapons that has special internal ballistics, allowing it to be fired from confined spaces; tight jungle, in front of obstacles or even with own troops in close vicinity. Both these features make it the only anti-armour weapon in the world that can be used to the full urban combat. The AT-4 CS HP rocket launcher is manufactured by a Swedish Company.

The AT4CS HP is based on same manufacture as the basic model AT-4, only the ammunition used change. AT4CS HP combines the light weight and firepower characteristics of the AT4 systems with the ability to fire from confined spaces and other narrow firing positions. Where conventional light anti-tank weapons would force the gunner to leave cover for a more open and exposed firing position, the unique internal ballistic design of the AT4CS HP system allows for maximum use of the protection offered by the urban environment.

Sight

The AT4CS HP sights are iron sights and are similar in concept and use to those on assault rifles.

AT4CS HP is disposable and preloaded with a specially developed High Penetration (HP) warhead. This provides the soldier with a weapon capable of defeating armour thicknesses exceeding 500 mm, which is more than enough to defeat most types of armoured targets on the urban battlefield.
